From: Luciano Coelho Date: Fri, 25 Jan 2013 10:05:34 +0000 (+0200) Subject: wlcore: move wl12xx_platform_data up and make it truly optional X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cc9efed707c575a9e5880ea68f8b9d36b235f1f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git wlcore: move wl12xx_platform_data up and make it truly optional The platform data is used not only by wlcore-based drivers, but also by wl1251. Move it up in the directory hierarchy to reflect this. Additionally, make it truly optional. At the moment, disabling platform data while wl1251_sdio or wlcore_sdio are enabled doesn't work, but it will be necessary when device tree support is implemented.
